Problems solved by technology

[0004] In the prior art, although the support structure of the foundation pit of a super high-rise building can prevent the springback deformation of the soil at the bottom of the foundation pit when the foundation pit is excavated, the support structure also has the following defects: The weight load will cause a certain deflection and deformation of the bottom plate of the foundation pit structure, and the diffused additional stress will also cause damage to the foundation pit structure

Abstract

The invention discloses a load-bearing enclosure system for a foundation pit of a super high-rise building, which includes a main frame of the foundation pit. The main frame of the foundation pit is composed of an upper frame, a lower frame, a supporting structure and a surrounding wall. The root support structure is fixed and supported; the lower frame is provided with several bearing piles extending into the foundation, and the upper end of each bearing pile is fixedly connected with the lower frame; the upper frame and the lower frame are equipped with several piles located in the horizontal plane The horizontal load-bearing structure and the vertical load-bearing structure; the adjacent support structures are connected with horizontal support structures. The invention effectively improves the water-stopping effect on the foundation pit, ensures that the settlement and deflection deformation of super high-rise buildings will not damage the foundation pit, and optimizes the overall planning of the completion period.

Description

technical field [0001] The invention relates to a building foundation pit support structure, which belongs to the field of soil engineering construction, and more specifically relates to a super high-rise building foundation pit load-bearing enclosure system. Background technique [0002] With the continuous development of urban construction, there are more and more various types of underground engineering and deep foundation pit engineering, and the construction method of deep foundation pit with high efficiency, economy, energy saving and environmental protection is particularly important. At present, the traditional deep foundation pit construction method is open construction, and its method is to excavate vertically after being surrounded by supporting structures or excavate with large slopes. After excavating to the design elevation, pour the reinforced concrete floor, then construct the basement structure layer by layer from bottom to top, and then carry out the constr...
